Agapology takes its name from the Greek word agape (ἀγάπη)—self-giving love that seeks the good and flourishing of another—and -logy, meaning the study of. Jan Armstrong infused this philosophy into a modern, applied framework, using it to ask a practical question: what if love were treated not as sentiment, but as a working system for human life? Drawing from theology, pastoral experience, leadership, grief, and his engineering background, Agapology explores how love can shape decisions, relationships, institutions, and communities. In Jan’s words, love is not “sentimental decoration,” but “the deepest architecture of durable human flourishing.”
